HEATER.

T 0 all whom it may concern: I

Be it known that I, GEORGE E. Ri'imn'r, a citizen of the United States,reslding at Eric m the count of Erie and State of l a Pennsvlvania haveinvented new and useful Improvements in Heaters, of which the followingis a specification.

This invention relates to heaters and consists in certain improvementsin the construction thereof as will be hereinafter fully described andpointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:Figure 1 is a side elevation of the heater, a part of one of the returnpassage manifolds being removed to better show construction. Fig. 2 isan elevation, the view being from the right of Fig. 1, the side coverbeing removed and a part of the heater being shown in vertical sectionthrough the center of the heater. Fig. 3 is a view of a fragment at theends of the heater tube as on the line 33 in Fig. 1. Fig. 4 is aperspective view of a fragment of one of the heater sections. Fig. 5 aperspective view of a series of the sections, one of the sections beingdrawn out to better show construction. Fig 6 is an elevation of theinside of the passage manifold. Fig. 7 is a section on the line 77 inFig. 1.

1 marks the heater sections. These are made of the tubes 2 which extendacross the heater. These sections are cast and the end portions 3 aresurfaced. The sections are laid up one upon the other, the heater havingthe bottom section 4. and the top section 5 with an inlet 6 and outlet 7for the heating medium, ordinarily steam. The bottom section is providedwith lugs 4 into which the legs 49 are placed for supporting the heater.Plates 8 are arranged at the side of the sections 1. Studs 9 are screwedinto the faces of the ends 3 and extend through the sides 8. Nuts 9 arearranged on the studs. In this way the sides of the heater are inclosed.

The passage manifolds or covers 10 and 11 are arranged over the ends 3of the sections. Studs 12 are screwed into the faces of the ends 3 andnuts 13 are arranged on these studs. In this way, the passage manifoldsare secured on the ends of the sec-.

tions. The passage manifold 10 has the inlet manifold passage 14 whichcommunicates with the inlet 15. Liquid is admitted to the manifoldpassage 14 and passes into Specification of Letters Patent.

the series of openings in the heater. section at the top. Passingthrough these tubes,

it passes into the passages 16 in the passage manifold 11. These passaes 16 connect the tubes of one heater section with another.

Itwill be noted that the tubes of the alterfolds, that is, with thebridge piece 11, the

joints 19 between the differentsections need not be made tight as theclosure on the surface 18 is entirely sufficient. This obviates troublefrom warping or other difliculties usually encountered in making thejoints of different sections of a heater tight. The liquid after passingthrough the entire series of heater sections passes out of the bottomseries into the manifold passage 20 and is discharged at 21. The heatersec tions are preferably weakened between each tube at 22 so that ifthere is any strain, these parts of the section will yield.

lVhat I claim as new is 1. In a heater, the combination of a series ofsections formed each with a cross tube with joint surfaced ends arrangedone upon another; and covers for the ends having ferent sections, saidpassages having bridge pieces forming closures for the joint between thesections.

2. In a heater, the combination of a series of sections formed each witha series of cross tubes joined in joint surfaced ends, said ends beingarranged one upon another; and passage manifolds for the ends havingpassages therein connecting the tubes of difierent sections, saidmanifolds having bridge pieces forming closures for the joint betweenthe sections.

3. In a heater, the combination of a series of sections formed each witha cross tube and joint surfaced ends, said ends being arranged one uponanother; a passage manifold for the ends; and means for tying thesections together, said manifold having passages therein connecting thetubes of the diflerent sections, and said manifold having a bridge piecewithin the passages forming a closure for the joint between thesections.

4. In a heater, the combination of a series of sections formed each of aseries of cross tubes joined together in joint surfaced ends, saidendsbeing arranged one upon another, the tubes of each alternate sectionbeing varied to give the tubes in the united sections a staggeredrelation; and passage manifolds arranged on the said section ends andforming a means of connection between the tubes of different sections.

5. In a heater, the combination of a series of sections each formed witha series of cross tubes with joint surfaced ends, said ends beingarranged one upon another; removable covers secured to the ends of saidsections for inclosing the sides of the heater; and passage manifoldsfor the ends of the sections forming a means of connection be tween thetubes of different sections.

6. In a heater, the combination of a series of sections formed each witha series of cross tubes with joint surfaced ends, said ends beingarranged one upon another; and a cover having passages connecting thetubes of different sections, said cover being arranged with a manifoldpassage for delivering the liquid to a series of the tubes in thedelivery section.

7. In a heater, the combination of a series of sections formed each of aseries of cross tubes with joint surfaced ends, said ends being arrangedone upon another, the said ends being weakened between the tubes for thepurpose described; and means for connecting the tubes of one sectionwith another.

8. In a. heater, the combination of a series of sections formed eachwith a series of cross tubes with joint surfaced ends; a passagemanifold arranged with a series of tubes connecting the tube of onesection with the tube of a succeeding section, said passage manifoldhaving a manifold passage at its ends for connecting all the tubes ofthe delivery section with the delivery and all the tubes of thedischarging section with the discharge; and plates closing the sides ofthe heater.

9. In a heater, the combination of a series of intermediate sectionsformed with tubes and joint surfaced ends; plates connecting the tubesof different sections at the ends forming a connection between thedifferent sections; and end sections having discharge and deliverypassages, for the heating me dium, said end passages extendinglongitudinally of the heater.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
